How wide of a footing for 12″x12″ brick support columns?

I’m working on a quote for a 1800’s era house in Galena KS. The wood columns supporting the sleeper porch have settled over 6″. The posts are supported by 12″x12″x24″ brick columns. I’m planning to remove the old columns, dig a foundation, and replace the columns. I plan to go 30″ below grade for the foundations. Is the width of the column itself wide enough? I read somewhere it should have an apron. Also, any suggestions on how much to charge?
Thanks!

For a 12"x12" brick support column, the footing should typically be 24"x24" and 12 inches deep to ensure proper stability. However, it's best to consult local building codes for specific requirements.
Here's the deal for a 12" x 12" brick support column you’re gonna want a footing that’s at least 24" x 24". Standard rule of thumb is the footing should be about twice the width of the column for proper support. But don't forget, this all depends on a few things like how much weight the column is holding and the type of soil you’re building on.
You also need to make sure the footing goes deep enough to get below the frost line if you're in a colder area. Typically, footings are anywhere from 12 to 24 inches deep, but again, local codes might require more or less depending on conditions.
Best bet? Double-check the load requirements and soil conditions, and if you're not sure, bring in an engineer. But for most jobs, a 24" x 24" footing is gonna get the job done.
